How-To Build a 4’ M416 Camping Trailer

We designed our Dinoot M-Series M416 camping trailer tub kits to have the same 40.5″ width that a M416 trailer has to be used as replacement tubs. This also makes them the same width as a Harbor Freight 40.5″ x 48″ frame kit. The Harbor Freight frames are perfectly sized for building a stubby 4′ M-Series M416.

Here is what a 4’ M416 camping trailer might look like:

Here are a few ideas on how you could build one.

Using a Harbor Freight Haul-Master #62645 40.5″ x 48″ frame kit, I would first stretch the tongue with a piece of 2.5″ square tube

Add reinforcement plates where the tongue bolts to the cross-members is an important step.

Another possibility would be to make the tongue long enough for using a Harbor Freight receiver cargo basket as a front rack

The final piece is the tub kit. Just like a full length M-Series M416 tub kit; you could build it with or without a tailgate. We have done this for the 5′ versions. We cut the side panels to the proper length for you before sending them.
